**Principal Data Scientist (ML, AI, CI) (for Customer Intelligence & Artificial Intelligence Team)**

**Duties and Responsibilities**:

- Constantly work with massive amounts of structured data and unstructured data from **relational databases (e.g. SQL in BigQuery) and non-relational databases (e.g. Graph Query Language).**
- ** Custom formulations, implementations, building & evaluating of different ML (Supervised, Semi-supervised, Weakly-supervised, Unsupervised, Deep, Reinforcement, etc.) models, Probabilistic and (Bayesian) Statistical models, Mathematical models, Algorithms, Optimizations, etc., using custom data collection & annotation methods, custom metrics, etc.**
- Custom implementations of data structures & algorithms in Python, C and C++ (to deal with huge amounts of data & hard problems), being aware of space and time complexities and hardware.
- Implement research findings, perform R&D, etc. in code to solve business problems.
- Performance & memory optimizations of programs, algorithms, etc. using **C, C++ & Python (Numba, Cython, Pythran)** to solve large-scale problems dealing with massive amounts of data.
- Creating high-performance local APIs and SDKs of outputs to hand-over to Data Software Engineers for them to build data & software products & services by building upon these outputs.
- Work with Data Software Engineers to make use of different sources of huge amounts of data, and so that they can build and deploy data products and services around the project outputs.
- Regularly communicate well and present deliverables to business stakeholders, etc.
- ** Highly skilled & experienced **_Individual Contributor_** track.**

**Qualifications & Requirements**:

- BS/MS/PhD in Data Science, ML, AI, Computer/Software Engineering, Mathematics, Computer Science, Statistics, Natural Language Processing, Computer/Machine Vision, or related fields.
